WILLIAM LIGHBODY, OF LONDON, ENGLAND.

HURRICANE-LANTERN,

SPECIFICATION forming part of Letters Patent No. 519,406, dated May 8,1894. Application filed June ]6,1892. Serial No. 436,969. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM LIGHBODY, a subyect of the Queen of GreatBritain, residing at London, England, have invented new and usefulImprovements in Hurricane-Lanterns, of which the following is aspecification.

This invention relates to improvements in hurricane lanterns and has forits object to provide an improved wind protector or means for preventingthe free access of wind through the space between the globe andair-chamber into the said globe.

In carrying out my invention I employ a perforated plate or screenplaced directly on the top of the globe of the lantern so as to movewith it or the plate or screen may be pivotally suspended and soweighted that, when the globe is tilted, the perforated plate is movedto allow the said globe to pass and remains in this position until theglobe is returned when the perforated plate will again fall onto the topof the globe. In combination with my plate I advantageously employ it)plain or perforated tube inside the air-cham- To enable my invention tobe fully understood I will describe the same by reference to theaccompanying drawings, in which Figure l is a sectional elevation of ahurricane lantern having my wind protector fixed upon the top of theglobe; and Fig. 2 is a sectional elevation of a hurricane lantern inwhich the wind protector is pivotally suspended above the globe. Fig. 3is a section on the line a; as, Fig. 2, showing my perforated plate orscreen. Figs. 4, 5 and 6 are elevations showing difierent arrangementsfor carrying my perforated plate or screen.

Similar letters of reference indicate corresponding parts in the severalfigures. I

0. indicates the burner and reservoir of a hurricane lantern, b theglobe thereof, and c the gallery or holder for the said globe, all ofwhich parts are of ordinary construction.

(1 indicates my perforated plate or screen. As shown in Fig. 1 thisplate or screen which is of. a curvilinear or dome-shape is fitted uponthe top of the globe and held in place thereon by means of spring-clipsd, d which clip upon the rib b of the globe.

In the arrangement shown in Fig. 2 the plate or screen at is carrieduponpivots e, 6 adapted to yield vertically to allow the necessary up .anddown movements of the said plate or screen when opening and closing thelantern. The pivots e, e are supported by hangers f, f attached to thehead g of the lantern, slots 71, it being provided in which the pivotse, 6 can slide during the up and down movements of the plate d.

In order that the plate 01 shall, when the lamp is opened, assume theinclined position shown in Fig. 2 so that, during the closing of thelantern, it shall offer no obstruction to the free movement of theglobe,I weight one side of the same. As shown clearlyin Fig. 3 thisweight consists of a wire 71 secured to the said plate (1, the ends ofthe said wire being bent to form the pivots e, e. With this arrangementit will be understood that when, during the closing of the lamp, theglobe b is moved from the position shown in dotted lines in Fig. 1 tothat shown in full lines, the top of the said globe will impinge againstthe under side of the perforated plate (1 and lift the same sufficientlyto allow the globe to pass freely beneath it, and that, when the lamp isclosed, the said plate will drop upon the top of the globe by gravity.

In the modification shown in Fig.4, the pivots e, e of the plate (1 arecarried by vertical rods j,j depending from and adapted to slide freelythrough the flange k on the head g of the lantern. l, lare guides, oneof which is arranged in conjunction with each of the rods j for causingthe same to move vertically.

In the modification shown in Fig. 5, I employ rods 7',j fixed to theflange lqbut instead of suspending the perforated plate (1 by means ofpivots e, e, I pass the said rods through holes in the flange 'm. of thesaid plate d, the holes being of sufficient size to allow the plate tomove freely thereon.

In the modification shown in Fig. 6 the perforated plate (:1 isrepresented as being carried by hinges n,one part of each of which issecured ,to the head g of the lantern while the other is secured to theperforated plate itself.

Although I have described and illustrated my perforated plate as beingweighted on one side in order that it may assume an inclined position itwill be obvious that the weighting may be efiected by pivoting it at oneside of a diametric line.

1. A hurricane lantern, having in cornbina j tion with a swinging orhinged globe, a dome shaped perforatedplate or screen fitted to andresting on said globe and supported on vertically movable pivots, andweighted at one side, substantially as set forth, and whereby when theglobe} is tiltedthis plate may by its own" gravity assume an inclinedposition and so remain until the globe in returning to 1ts uprightposition, impinges upon the under side of the plate, lifts it up andallows the globe to pass freely beneath it, the plate then droppingt'oits place on the globe.

2. In combination with the swing gallery and its, globe, and with theperforated screen or plate attached to and swinging with the globe asset forth,'the air chamber above the same'gand thegperforated tube 0. 0.within said chamber, all substantially as set forth.
